Hood has a decent public park...though it can be pretty rough early in the morning if it froze solid the night before. Going past the camps parks to the public park though makes you realize how much better those places are.
ya, last years whistler park had like 4 rails and a couple jumps, but there was a rail jam while i was there and you can still ski some other stuff too.
well when i hit up whistler their public park kinda sucked. they had a half pipe that had like holes in the wall and a couple sick rails but thats it. no jumps or anything other than pipe and rails
